Must admit the snapper snooping has been bettered by softbaiting though!

Yeah,years ago I was commercial construction diving on the Cook Strait power cables out of Oteranga Bay and saw a couple of Nuiean freediver spearos(human seals) hunting the coast kelp beds and bringing out strings of butters etc, so started targeting em myself and subsequently kept the family and all our annual summer camp families well fed on bounty from the central HB coast . Moved north 10 yrs ago so Coromandel gets frequent forays and provides nicely.
